Concentration of digestible and metabolizable energy and digestibility of energy in high protein canola meal, conventional canola meal, and soybean meal fed to growing pigs

Canola meal is the defatted meal that remains after oil has been extracted from the seeds of the rapeseed plant, Brassica napus.  Canola meal is high in crude protein and amino acids relative to most plant protein sources, and the amino acids in canola meal are well digested by pigs. However, it is also relatively high in fiber, which reduces energy digestibility and digestible energy concentration. New varieties of Brassica napus with a thinner seed coat have been hybridized, which contain less fiber and more protein than conventional rapeseed. The meal produced from these varieties is known as high protein canola meal. No data exist for the digestibility of energy in this source of high protein canola mealwhen fed to pigs. Therefore, an experiment was conducted to determine the apparent total tract digestibility (ATTD) of energy and the concentrations of digestible and metabolizable energy in two sources of high protein canola meal (CM-HP1 and CM-HP2) fed to growing pigs, and to compare these values with values for conventional canola meal (CM-CV) and soybean meal (SBM).
